Application filed. May 15,1925. Serial No. 30,430.

This invention l'0l1 to improvements in The apertures 18 of the clamp 18, and

center mount for car boiler and has for its ohicct to pro vide new and improved mountwhich will aliord an increased bearingtor pivotal movement while pcri'nitthe use of a compact construction, and 'r'h construction will permit the ready mbly and disai-iscmbly when desired. his and other objects will be more fully forth in the following specification and in the accompanying drawings in which,

refer to like elements i hout the drawings, in which indigenerally the car end, to which are ated the buffer end brackets 11, the beldiaphra in 12, and the diaphragm face e 13. l ro eciiiug inwardly from the face is a center cricket 1% comprising .c top and bottom portions H in. which are provided the aligned apertures 14 into whicn project the rounded lugs i l. A pivotpin 15 is provided having an angularly bent top 15*, this pin being convened at one side indicated by numeral 15 and being concave-d at one side at (see Figs. 3 and 6).

Le) 3* butler spring 17 is provided of laminated construction, its ends being secured in known manner to pivoted links mounted in the end brackets 11 (see my prior Patent, 1,514,?) 3, Nov. t, 1924). At the center 0'? the spring 17 are provided the spring clamps l8 and 19 (see 2, 3 and 4), the former being of three sides, the top and bottom 18 being provided with apertures 18, substantially semi-circular in form. Coacting with the clamp member 18 is the member 19 having the central vertical groove or depression 19. Rivets 20 extend through the spring leaves and secure the clamping members 18 and 19 in assembled relation, as shown in Fig. 3.

the groove 19 of clamp 19 form, with the spring itself, a socket or passage -for the pivot-pin 15, which has the flattened edges 15 contacti; ith the spring shown in Fig. 8, this arrangement being such as to prevent relative rotat-ive movement of the pin 15, with respect to the spring and clamps. The apertures 14; of lugs 14 are so con structed as to permit bearing of the convex portion or" the pin against the bracket is or vice versa. or permit bearing contact be tween the rounded lugs 14 and the concave portion of pin 15 as the spring is compressed under butling strain, or expands in the absence of the same.

i l/hen diaphragm plate is rotated or rocked to a vertical axis when the car is in turn or rounding a curve or the like, this movement will be permitted without cramp ing the spring 17, due to the pivotal mount ing of the spring center in the bracket 1%, the kidneyshaped apertures l t" being suficiently extended as incicated in dotted lines in S to permit the necessary rocking 1novement.

As described above, the pivot-pin 15 is held against relative rotation with respect to the spring, and provides a species oi journal for he center bracket 1%. its segn'ienzal. concave-convex construction provides a hearing surface, both when the spring is expanded or compressed without necessitating enlarged construction of the bracket i l and associated mechan sm. At the same time, the pin may be easily removed by lifting it from assembled relation after removal oi the cotter or split-pin 25, which extends through the lower end.

It Will be obvious that my invention is susceptible of modification and I do not wish to be restricted to the form shown and described, except as defined in the appended claims.

What I claim is:

1. In combination with a movable plate a bracket carried thereby, a spring, seg mental pivot-pin carried by said spring and having an arcuate bearing surface, said bracket being provided with hearing surfaces to contact with the bearing surfaces of said pin.

2. In combination with amovable plate a supporting bracket carried thereby, a

complementary convex and concave bearing surfaces.

4. In combination with a movable plate a supporting bracket, a spring, a pivot-pin carried by said spring, said pivot-pin being of elongated, non-circular cross-section having a bearing surface at its outer and inner sides, said bracket being provided with complementary bearing surfaces COZH'iJ- in with the bearing surfaces of said pin.

In witness whereot. I hereunto subscribe my name to this specification.
